Why do messages arrive with a significant delay when using a VPN

The situation is familiar to many: you turn on your usual network security tool, and suddenly, chatting starts to resemble carrier pigeon correspondence. Notifications arrive five or ten minutes later, or sometimes require you to open the app to force a feed update. Why does this happen, and can you restore instant delivery without sacrificing security?

How a VPN affects message receipt speed

When a messenger is running normally, a message follows a short path: from your device to the provider's servers and then directly to the recipient. This route is optimized for transmitting the tiny data packets that make up text messages. As soon as you activate a third-party service to change your location or protect your traffic, this path is artificially lengthened. Data is forced to first go to an intermediate node — a server in another country — and only then travel to the recipient. At PING, we emphasize a clear signal: the user should quickly understand what is happening in the conversation. Additional links in the transmission chain always add “weight” to each request, turning instant exchange into a sequence of micro-delays that add up to noticeable waiting times.

Why network delays occur

The main reason for delays lies in the specifics of network protocols. Most messengers use specific communication channels that require a constant “handshake” between the server and your device. A VPN service encapsulates all your traffic, wrapping it in additional packets. If the VPN server's bandwidth is low or it is located on another continent, the network packet may be lost or arrive with a delay (high ping). As a result, your smartphone does not receive the signal about a new message on time, as the connection “goes to sleep” while waiting for a response from the remote gateway.

Diagnostics: how to determine if the network is the bottleneck

Before changing device settings, it is important to localize the problem. The fastest way is to temporarily turn off the VPN. If messages start “arriving” instantly after deactivating the service, the problem lies in the quality of the connection to the intermediary server. It is important to understand that many public VPNs are overloaded and their bandwidth is unstable. If delays persist even with the VPN turned off, it is worth checking if “Battery Saver Mode” is enabled on your smartphone, which forcibly limits background app activity to save power. Operating systems often aim to “put to sleep” background processes to extend battery life, and messengers are often the first to be affected.

Checklist: how to restore communication speed

If working on the network through third-party tools is necessary, try the following steps to restore a comfortable pace of communication:

  • Select another server: Geographical proximity to you often solves the delay issue. If you are in Europe, choose a server in the European region.
  • Background activity settings: Ensure the messenger is allowed “Background Activity” in your operating system settings. Systems often reset these permissions after a software update.
  • Traffic exclusions: Many VPNs allow you to set up “Split Tunneling.” Add your messenger to the exclusion list so it works via a direct connection, while the rest of your traffic goes through the secure tunnel.
  • Check network filters: Ensure there are no active antiviruses or firewalls on the device that may incorrectly flag encrypted traffic as suspicious and delay its processing.
  • Clear cache: Temporary app files can accumulate, creating conflicts during network reconnections. Regularly clearing the cache helps the app restore connection with the server faster.

Remember: clear communication requires a stable channel. Sometimes it is enough to simply change the entry point or switch from Wi-Fi to a mobile network for messages to stop “hanging” in transit. If the problem remains critical, try temporarily using a different connection protocol provided by your VPN provider, as some of them (for example, TCP vs. UDP) work much more stably under an unstable internet signal.

Frequently asked questions

Why are delays considered normal when using a VPN?

A VPN creates additional distance for data transmission and adds a layer of encryption, so minor delays are unavoidable. However, if delays amount to several minutes, it usually indicates that the chosen VPN server is overloaded or its protocols are unstable.

What should I do if messages arrive with a delay even when I turn off the VPN?

If the problem persists without a VPN, the issue lies in your phone's settings or your provider. Check your battery saver mode, background activity permissions for the app, and clear the cache — this often resolves delivery issues.

Can network filters slow down message delivery?

Yes, security systems and firewalls can classify proxy traffic as non-typical and temporarily restrict data transfer speeds or hold them for additional inspection, which directly affects notification delivery.

Data Security: How to Check App Access to Your Account

We explore how app permissions work, why we forget about granting them, and how you can easily check third-party service access to your account to boost your digital security.

We are used to the fact that our digital lives consist of many services. From photo editing and task planning to searching for travel tickets, we install dozens of apps for everything. Often, when registering for a new service, we click "Log in with" or "Grant access to profile" without thinking about what kind of "keys" we are actually handing over to a third-party program. Tidying up your profile security is easier than it seems, and it is a great habit for digital hygiene.

How we give apps the keys to our account

When you see a prompt to "grant access to profile," the application usually requests a minimal set of permissions: your name, email address, or photo. However, developers sometimes request the ability to read messages or view contacts. Most users click "Allow" automatically to start using a useful tool faster. Over time, this accumulates a list of applications that you once granted access to, but no longer remember. This is where the risk lies: if a third-party service turns out to be unscrupulous, it could use this channel to access data that it shouldn't have constant access to. This does not mean every service wants to harm you, but it is worth remembering that the fewer permissions an application has, the higher your overall profile security.

Step-by-step diagnostics: where to view the permissions list

Checking app access to your account is not a technical quest, but a simple process that can be done in a few minutes. In the settings of any major email service or social network, there is a section called "Apps and Devices" or "Connected Services." It always displays an up-to-date list of connected services that have the right to interact with your data. If you see the name of a game you deleted a year ago, or a service you stopped using, that is the first candidate for revoking access. It is important to do this calmly: review the list, highlight suspicious or old entries, and assess whether they really need access to your information right now.

How to restrict permissions and revoke unnecessary access

The process of "clearing your permissions history" usually consists of a single click on the "Delete" or "Revoke Access" button next to the relevant application. As soon as you do this, the service will immediately lose the ability to access your data. How to set a password for your correspondence — this is a question that often arises for those who want to further protect their data, and revoking permissions is the first step in this direction. It is important to remember: revoking access does not delete your account in the third-party service; it only closes the "window" for the application to automatically collect information from your profile.

A clear signal — a calm response

Digital security is built on understanding who has access to your data and why. We believe that privacy should not be a complex setting that you have to spend hours looking for. At PING, we focus on a clear signal: the user should quickly understand what is happening in their correspondence. Because our privacy settings are always transparent and under your full control, you can focus on communicating rather than checking who is "peeking" at your actions.

Frequently asked questions

What happens to my data if I revoke an app's access?

Your data does not disappear, but the app can no longer access it automatically. Previously obtained data remains with the developer, so it is important to trust services before granting them permissions.

Is it safe to use "Log in with" buttons on third-party services?

Using this feature is convenient, but always pay attention to the confirmation window: it always lists exactly which permissions (contacts, messages, profile) you are granting.

How often should I check the list of apps with access to my account?

We recommend conducting a review every 3–6 months. It takes only 5 minutes but helps remove outdated connections and protect your account from unnecessary access.

How to safely interact with AI bots and protect personal data

We explore how data processing algorithms work in chatbots, why it is important to disable training functions on your prompts, and how to interact with neural networks without putting your privacy at risk.

How to safely interact with AI bots and protect personal data

Artificial intelligence has become a reliable assistant in our daily lives. We delegate tasks to neural networks, such as creating to-do lists, drafting emails, and structuring disorganized information. However, convenience hides an important privacy question: what happens to messages the moment we hit send? Many users treat interactions with a bot as a personal conversation, but in reality, it is an interaction with a mechanism that often uses incoming data to train its models.

Understanding how modern neural network tools work is the first step toward digital safety. When you send a prompt, the information does not disappear without a trace. In most cases, it is analyzed so the algorithm can become more accurate and useful. For the user, this means that potentially sensitive information could become part of a training set if service permissions are not restricted in time.

Why you should think about the security of your correspondence with AI

The security of interacting with neural networks is built on the transparency of data retention policies. Most popular services store your query history by default. The main reason is to customize the experience and improve the quality of responses. But from the user's perspective, this means losing control over where the text you have written ends up. It is important to remember: if privacy settings have not been adjusted manually, the information you share may be stored on the developers' servers for a long time.

To protect yourself, follow this rule: any chat with an AI is a space where you should not share secrets. Imagine you are not talking to a trusted individual, but to a public archivist who methodically writes down everything they hear for their collection of knowledge. By excluding passwords, card details, addresses, and names of colleagues from your correspondence, you will already make a significant contribution to your personal security.

How to configure privacy when using neural networks

Modern platforms are increasingly providing users with tools to control their data. You do not need to give up technology to maintain privacy; you just need to change your approach to settings. Here is your basic checklist:

  • Find the "Data Controls" or "Privacy Settings" section in the bot's user account.
  • Disable features like "Improve model with your data" or "Chat history & training".
  • Regularly delete your request history if the service does not offer automatic clearing.
  • Whenever possible, use "temporary chats" or "incognito mode", which do not save the context of the correspondence in the long term.

These actions do not negate the convenience of using AI, but they create a necessary defensive barrier between your personal data and the developers' training algorithms.

Digital hygiene and real communication

When it comes to truly personal communication, the methods of data transmission must be different. At PING, we emphasize clear signals: a user should quickly understand what is happening in a correspondence. Unlike complex neural network environments where your messages can become part of a training set, here you control who sees your text. Clear communication means the absence of hidden processes and the certainty that your words belong only to you and the recipient. If you need to share important location data or personal information, choose tools with transparent security policies and end-to-end encryption, rather than those focused on collecting and analyzing content.

Confidentiality of correspondence is the foundation of digital hygiene. AI assistants are indispensable for work tasks, but they should not know the secrets of your personal world. If information requires a high level of protection, always prioritize proven tools where your data is not used for external algorithm training. Peace of mind begins where you know for certain: your message is secure and accessible only to those you addressed it to.

Additional context on the topic is provided in the article How to safely share location data.

Frequently asked questions

Is dialogue data with AI bots stored?

Most models save chat history by default to improve performance. If you do not disable this option in the privacy settings, your queries may become part of the developer's database.

Do AI models train on my private messages?

This depends on the specific service's policy. Many companies use user data to train models, so it is crucial to disable the relevant settings in your account.

What data should never be shared with AI assistants?

Never transmit passwords, document numbers, bank card details, residential addresses, or any other information that could be used to identify you or your loved ones.

Profile Security: What is Two-Factor Authentication

When you log in to a messenger, the system must be sure it is really you. Previously, a password was the only barrier, but today that is not enough: if a password leaks online, your account is at risk. This is where two-factor authentication comes in as an essential standard for digital hygiene. It acts as a "second lock" on the door of your private correspondence, reliably protecting your data even if an attacker discovers your primary key.

Why extra protection is needed: From passwords to verification

Many users perceive two-factor authentication as an annoying obstacle: why enter extra codes if you just want to open a chat and start talking? However, in reality, account protection is built on a balance between convenience and security. When you enable a second factor, you create a line of defense that cannot be crossed without physical possession of your device or unique access to biometric data.

If someone tries to log into your profile from another device, the service will require verification. Without it, access will be blocked, and you will receive a notification about the login attempt. This allows you to avoid panic and immediately curb any unauthorized activity.

The difference between SMS codes and modern authentication methods

Classic SMS codes were the standard for a long time, but they are vulnerable: a mobile signal can be intercepted, and a phone number can be spoofed. Modern authentication methods, such as using biometrics or confirming a login via an already trusted device, work differently. Why is biometrics more reliable than a password in a messenger? Because your fingerprint or facial data is unique and physically tied to a specific device. They are not transmitted over the network but are checked locally by your phone's security system. Unlike a code from a text message, a biometric key cannot be spied on or intercepted at the carrier level.

How modern authentication works in apps

Modern login methods are based on the trusted device principle. If you authorize in an app on a new smartphone, the system sends a request to an already active device. This eliminates the need to enter one-time passwords. Why confirm a login via another device? This rules out situations where your account could be opened by anyone simply having access to a SIM card. You become the sole holder of the "key" to your digital profile.

How to set up account protection and stop worrying about hacking

Setting up protection does not require deep technical knowledge. At PING, we focus on a clear signal: the user should quickly understand what is happening in their messages. Therefore, we strive to make the second-factor activation process as simple and clear as possible. To protect your messenger account with a fingerprint, simply go to your security settings and turn on the corresponding option. After that, every important action will require a brief confirmation via biometrics. It is not only reliable but also convenient: you do not need to memorize complex passwords, as the system "recognizes" you instantly, making communication secure and peaceful.

Frequently asked questions

Why is confirmation via another device more reliable than an SMS code?

Confirmation via another device links access to a specific, already-trusted gadget. Unlike SMS, which can be intercepted or compromised on the carrier side, this method requires physical access to your device, making it virtually immune to remote hacking.

How safe is it to use a fingerprint for login?

Biometric data (fingerprint or FaceID) is stored in the secure area of your phone and is never sent to the app's servers. The app only receives a "success" signal from the device's security system, making this one of the safest login methods.

How can I avoid losing access to my account with double verification?

The main rule is to keep backup codes in a safe place (e.g., offline notes or a password manager) and ensure that at least one trusted device is always at hand. If you change your phone, authorize on the new device first before deleting the messenger from the old one.
